The Other: Ernest Crawley calls our inborn aggression to ethnic (and other) conflicts a “taboo of personal isolation.” Sigmund Freud says that it stems from our “narcissism of minor differences”. We compare ourselves to one another, constantly feuding and ridiculing each other in our minds. In an effort to set ourselves apart as unique or righteous, we focus on our “details of differentiation”. Is there any hope for our miserable self-centeredness?
Holy City: Isaiah pictures the Holy City as a place where those now at war—even predators and prey—will be at peace. He writes, “The wolf shall dwell with the lamb, and the leopard shall lie down with the young goat, and the calf and the lion and the fattened calf together; and a little child shall lead them. The cow and the bear shall graze; their young shall lie down together; and the lion shall eat straw like the ox. The nursing child shall play over the hole of the cobra, and the weaned child shall put his hand on the adder’s den. They shall not hurt or destroy in all my holy mountain; for the earth shall be full of the knowledge of the Lord as the waters cover the sea.” 
Shalom: In When the Kings Come Marching In, Richard Mouw writes, “In the glorious future, the Lord will eliminate conflict between animals, and between animals and human beings. Former predators will live peacefully with their former prey. Little children will have nothing to fear from beasts or snakes. The coming of the peace, the shalom, of the Lord has far-reaching implications. The fullness of the knowledge of the Lord will banish all hostility and enmity from the good creation. The curse of sin will be lifted from the earth, and God’s righteousness will heal all that was touched by it. Even relationships between animals will be transformed.”
Prayer: Lord, When we pray, “May your kingdom come on earth as it is in heaven,” the type of peace for which we long is the type that puts down the sharp sword and closes the growling mouth. And we want it to start with us. Mortify our narcissism that seeks to magnify our differences. Increase our knowledge of you so that we can put down our self-righteousness and pursue self-forgetfulness in Christ. Amen.
